Fallout 4’s main questline has dozens of quests and multiple ways for which it can branch out. Siding with one of four factions is required to finish the story, with arguably one of the most interesting factions to join being the Railroad. It offers a great mix of espionage and combat quests that no other faction questline offers.
One of the Railroad’s more interesting quests is the “Underground Undercover” quest. Players will need to work with an Institute scientist and a synth to prepare a rebellion inside the Institute and help every synth escape. For those looking to side with the Railroad, here is a complete guide to completing the “Underground Undercover” quest in Fallout 4.
11 Obtain And Upload The Encrypted Message
Once the player gets far enough in the Railroad’s quest chain, they will be tasked with making contact with an anonymous Institute scientist that has been helping synths escape.
To do this, players need to obtain an encrypted message holotape from Tinker Tom and upload it into any Institute computer.
10 Meet Patriot
Uploading the message will send a message to the player named “Urgent Reply.” Reading this message will reveal to the player that the Patriot is hiding in a maintenance closet and to meet them there.
Walking into this closet will reveal the Patriot to be Liam Binet. He is more than willing to work with the Railroad to free more synths. Before Patriot fully commits to helping, however, he has the player meet a synth named Z1-14.
9 Meet Z1-14
Z1-14 has been working alongside Liam and wants to help 13 Institute synths escape the facility when the time is right. In order for the synths to escape, they need to override the security of the facility with a password they don’t have.
At this stage, players need to report back to the Railroad to figure out where the password is.
8 Report Back To The Railroad
Talking to Desdemona will direct the player to P.A.M. It will tell the player that Wilfred Bergman, one of the original Pre-War C.I.T. scientists, has a password that should work.
While the Railroad considers Liam’s plan for escorting the synths to safety, P.A.M. instructs players to head to Cambridge Polymer Labs.
7 Get The Password From Cambridge Polymer Labs
Reach the Cambridge Polymer Labs and head to the laboratory section of the facility. Players should be able to find the password on a terminal on the second floor. It’s locked behind an Expert terminal password, but players can reach it by climbing through the ceiling passage nearby. Note that in order to leave the Cambridge Polymer Labs, players will need to complete the quest here in order to disengage the lockdown.
Head back to Desdemona at Railroad HQ. She will tell the player that she wants to help Z1-14 escort every synth out of the Institute, not just the 13 he mentioned previously. Return to the Institute and deliver the password and news to Liam Binet and Z1-14.
6 Give The Password To Liam Binet
Liam Binet can be found in the Institute in the same spot as before. Deliver the password to him and inform Liam that the Railroad wishes to work with Z1-14 for the rest of the operation
This concludes the Patriot’s role with this questline. Meet with Z1-14 to continue this quest.
5 Meet Z1-14 Once Again
Bringing up Desdemona’s idea to Z1-14 sparks doubt among him at first, but he does think it might be possible. At this stage, players will need to wait 24 in-game hours before talking to Z1-14 again. Sitting at any chair in the Institute will allow the player to wait for a certain period of time. Set it to 24 hours, wait, then return to Z1-14 for new dialogue.
After consulting other synths about the idea, Z1-14 believes it is possible. That said, they are severely unarmed. Z1 asks the player to kill a few Institute guards in the nearby tunnels and steal their weapons so the synths have some form of defense when they try to escape. They’ll stage the deaths as a construction accident, so players don’t need to worry about how they kill the guards.
4 Kill The Tunnel Guards
Between the Synth Retention and Robotics wings lies a maintenance tunnel that has the guards Z1 was referring to earlier. There is no restriction as to how they should be killed, but do note that they must be killed in a timely fashion. Taking too long to kill the guards will cause the Institute to become hostile and prevent further entry.
Speak to Z1-14 again once the guards are dead to receive his thanks. Depending on how far the player is in the main story will determine what they must do next.
3 Complete The “Powering Up” Quest
For players who haven’t progressed far enough in the Institute’s quest chain, they will need to complete every main quest up to and including the “Powering Up” questline. This includes “Synth Retention,” “The Battle of Bunker Hill,” “Mankind – Redefined,” “Mass Fusion,” “Pinned,” and “Powering Up” as the final quest.
Once players reach this stage, Father will instruct the player to take down the Railroad. A runner will soon appear and ask the player to talk with Z1-14.
2 Meet With Z1-14 One Final Time
Talking to Z1-14 will reveal that the Brotherhood of Steel has found the Railroad HQ and plans to attack immediately.
He asks the player to return to the HQ as soon as possible to inform the Railroad of the imminent attack. Z1 will prepare the rebellion during this time.
1 Warn The Railroad Of The Brotherhood
Head back to Railroad HQ and warn Desdemona of the attack. While it would seem that warning the Railroad would be time-limited, it isn’t. Players can complete this task whenever they see fit.
Once she is warned of the attack, however, the final quests of Fallout 4’s campaign will begin and lock the player to a specific faction. Warning her will complete the quest.
